The app situation is going to change very rapidly in the next few months. It's why Microsoft is making a big deal of the Windows 10 install base. There was a quick slide follow up in the devices announcement that showed that the growing install base has already attracted some big companies to the UWP [Universal Windows Platform] that previously had be meh on Windows Phone.

With Windows 10 on phones in November that platform will light up on phones finally. (Already the UWP Facebook app, as one example, is a leap forward in cross-OS feature parity compared to previous versions and it will be great to see that "day one" on Windows 10 phones.) On top of that you have "Project Astoria" which will mean very easy ports of existing Android apps to Windows 10 Phones for developers looking to leverage existing code investment. (Already somewhat released and being utilized is "Project Islandwood" and we're starting to see some iOS software ported to Windows through it.)

The UWP support on the Xbox One (and the merging of the Xbox and Windows Stores, huzzah) is supposed to light up as soon as November and we now know that a lot more developers will have access to HoloLens (which will also utilize the UWP) early next year. I think that access to Xboxen and HoloLens will encourage more developers to also consider cheaply scaling "down" to people's phones as well. So too should Continuum phones and their ability to offer side-by-side run "desktop-like" versions of UWP apps may drive some interesting apps to Windows Phone moving forward that have ignored it thus far.
